Summary
A series of biodegradable polyphosphazenes with amino acid ester side groups were prepared starting from the poly (dichlorophosphazene). It was demonstrated that the rate of hydrolytic degradation can be varied by introduction of small amounts of depsipeptide side groups. Some selected polyphosphazenes were used to prepare implant devices containing mitomycin C (MMC). In vitro release studies demonstrated that the release rate can be controlled by the amino acid side group composition. Initial in vivo data indicates that i.p. implanted devices show promise for the treatment of tumour bearing animals.
